Servomex releases SERVOPRO SO2 sulfur dioxide analyzer

August 18, 2017 – As part of its emissions monitoring analyzer range, Servomex announced the SERVOPRO SO2, an analyzer that uses pulsed Ultraviolet (UV) Fluorescence technology to deliver a continuous measurement of sulfur dioxide in emissions and ambient air.

The analyzer’s measurement is based upon UV radiation of the sulfur dioxide molecule using light in the range of 190-230 nm. The molecule absorbs the light into an excited state and then decays back down to the ground state, where a photomultiplier tube (PMT) converts the signal into SO2 concentration.
To prevent interference and quenching from polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, the SERVOPRO SO2 is fitted with a “kicker” to remove them from the sample before analysis, ensuring a reliable, accurate reading.

The analyzer is designed to slot into analyzer racks, making it easy to integrate with existing emissions monitoring systems, and offers data logging and remote viewing of more than 200 operational parameters.

The operational status of the analyzer can be seen at a glance thanks to an instant-response lighting system.

The SERVOPRO SO2 is part of Servomex’s emissions monitoring analyzer range set to meet the lower regulatory requirements, joining the SERVOPRO NOx, which uses Chemiluminescence Detection, the heated-oven, Flame Ionization Detection-based HFID, and the SERVOPRO 4900 multi-gas analyzer to offer a comprehensive solution for the monitoring of NO, NO2, NOx, O2, SO2, methane, total hydrocarbons, and non-methane hydrocarbons in a diverse range of industrial and vehicle applications.
